Pedra do Baú, Mountain formation in São Bento do Sapucaí, Brazil

Pedra do Baú is a rock formation in the Serra da Mantiqueira range that rises steeply from the surrounding landscape. The site consists of multiple peaks with distinct shapes and dominates the skyline of the region.

The first ascent was made in 1940 by the brothers João and Antônio Teixeira de Sousa, known as the Cortez brothers. Two years later the businessman Luís Dumont Vilares funded the first two via ferrata routes, on the south face above the Baú district and on the north face above São Bento do Sapucaí. A mountain shelter was later built on the summit; only its foundations remain.

The complex is made up of three named rock formations: Pedra do Baú, Bauzinho and Ana Chata. Since 28 December 2010 the area has formed the Pedra do Baú Natural Monument, a state conservation unit of 3,154 hectares within the Mantiqueira Mosaic. The site draws climbers and paragliders, and the foundations of Brazil's first mountain shelter, later vandalised, can still be seen on the summit.

The site is open during daylight hours and requires proper footwear for the slippery rocks. Weather changes quickly at this elevation, so bring a jacket and plan to arrive early in the day.

The area includes three different hiking routes leading to separate peaks, each with its own distinct character. This variety allows visitors to choose different experiences based on their ability and available time.
